How Much Faster Is A Car On Slick Tires?

@@rodtukker1904 Maybe for a short distance, because they would burst soon, I think. :D

[@andyowens5494]

@@rodtukker1904 Nope. At that point you will have worn away the grippy stuff, and you're left with the structural rubber - its tough, but not anything like as grippy. And its death-on-wheels in all but bone dry conditions.

Does shaving road tyres make much difference on a tarmac track? On dirt speedway I used to groove my tyres by hand and came up with improvements. I'd get about a meeting (30 400m laps) before needing to swap and rotate tyres, regroove them for the third meeting, and by the time that was over I had no tread block left to reshape. If I had the ability to shave tyres to reduce block distortion I would definitely have tried it to see if the tyres lasted any longer

I think we can all agree that every car guy has been wondering about putting slicks on at some point, and now we know we should, at least once. Then fall in love with it and spend all our money on tyres. 😂

😂 slicks or even semi slicks should be left if you're ultra rich or have a F1 team backing you with cash. Seems a costly hobby haha

I had semi slick Yokohama 17" 225 tires Advean Novea and I can tell that I was driving on rain 250km/h with no problems, braking, steereng etc. On sunny day it's like changing whole car in comparison with normal tires. It impacts whole performance. Skills and driving technics are equaly important if pushing to new limits but semi slick are my only tires for private car summer time.

[@tyrereviews]

haha, rear tyre temp was never really an issue after a warmup lap which surprised me. The car was setup for understeer though out of factory

[@damncritics]

It's probably easier actually because it means much more load on the tyre that's still touching the ground.

[@richardsmith5249]

I had a Mk I Golf that would do that, a lot of years ago. It had to be properly provoked, mind.

[@fredygump5578]

@@Drnken229 The truth is the exact opposite of what you said. The car is diving to the front outside corner because front springs (in combination with the suspension geometry) are too soft to prevent that amount of roll. And the rear springs are too stiff for this specific configuration. Why? Because it is a 4 door passenger car, not a single seat race car. If it was optimized for handling with just the driver, it would drive poorly when fully loaded.

I've always seen it as it's better to do tires and suspension before doing power mods. Power only helps during accel. Tires and sus help during accel, deccel and turning.

[@79blustone]

That real is a considerable time difference, coming down 3 seconds a set! That fuel surge would make me loose the plot. I'd love to see some tyre testing on GR Yaris as being the car of the moment, it would be interesting to see what a difference of tyres would make being a 4WD small hyperhatch.

[@tyrereviews]

It's surprisingly common, I had the same issue on an M2 at 1/3rd tank remaining :( Would love to test with the GR sometime, I've still not driven one!

@@tyrereviews Was that the Competition or pre 2018/9? I wonder if they changed the internal dimensions so the fuel pick up pipe doesn't starve? Epic car though 👌. You really need to drive one (Yaris GR with circuit pack), don't listen to the hype, make your own judgement, but it is crazy how it delivers power in each of the drive modes- (sport) rear bias pushes you into the corner the 'normal' setting gives you the feeling of pulling you into the corners much like a front wheel drive should- but with slight effort made from the opposing axle for a subtle bit of grip (can't be switched 100% to front or rear wheel only, 4WD still has a slight effect). The sheer cornering speed will have you grinning from ear to ear. Most of the torque is low down- quite similar to an E.V, its different from say an M3 or M4 Competition. Its a different type of fun, definitely try and borrow one for a tyre test! (Be careful as the wheels are £1600 each without tyres!)I could imagine a lot of people would be very keen to see something here. 👍

[@TheBlaert]

There's a serious difference. Years ago I did some hillclimbing. Pretty much standard cars but with suspension and bolt on tweaks. Tyre choice was probably the biggest difference. Started on a standard road tyre, then progressed to a softer compound and finally a road legal "slick". Absolutely crazy difference. Also tyre pressure made a shocking difference too

[@Sunny-s1de]

Higher or lower pressure for more grip?

[@TheBlaert]

@@Sunny-s1de slightly lower. Too low though and you risk the tyre coming off the rim

[@krzych91krk]

Looks like fun, but be aware. Road car suspension is not designed to handle this sort of G loads, so slicks will quickly wear out your stock suspension components/bushings. Exposed paint areas will suffer from the soft compound aggressively picking up all the rocks. Savagegeese made a good video on that subject.

[@johnhufnagel]

You gotta pay to play. painter's tape along the sensitive edges is always a good idea. It even comes in colors now so you can be decorative at track days! :D

Chris is spot on with his points……notably suspension components. Back in the day a friend used to track his car and tried slicks one weekend. Went faster than he ever had of course but the cost was it destroyed several of the control arm bushings (which were rubber still as it was still a street car) Never had that problem when he ran DOT R compound tires.

[@pgr3290]

Tried slicks on a Caterham R500, it was a bizarre feeling but once they were warm it would literally drive around the outside of anything on the track. I could walk around the outside of a 997 GT3 RS like it wasn't there. It was hilarious.

The front tires weren't just rolling onto the shoulder, they were right on the sidewall! Perhaps in the next video you could use a RWD car. I think a modern M3 (paddle shifts) would work well.

[@andyohara1393]

Awesome video and a great comparison for track day tyres. About twenty years ago now I had an E30 M3 Sport Evolution which was running around 275 bhp with twin injection running a stand alone Motec ECU, Shrick cams and a custom air box, it was stripped, fully caged and was running 3 way adjustable coil overs with adjustable anti roll bars (I know, sacrilege to do that to a Sport Evo, but back then they were only worth about £12K!). I used to run slicks on track and the thing was awesome, however, I was forever changing bushes and god knows what else due to running slicks. The slicks on track were a world apart from the Bridgestone S02's that I used as a road tyre and back in the day the S02 was a really good road tyre.

[@tyrereviews]

I loved the S02, and what a car that sounded like. Did you ever consider just replacing the bushes with metal parts so the wear would be less of an issue

[@andyohara1393]

@@tyrereviews Yep the S02 was an awesome tyre especially for the E30 M3. The M3 did end up being rose jointed and poly bushed, it was excellent on track but an absolute nightmare on road especially with the upgraded diff I was also running. It's one of those things where I wanted to always go that extra bit and ended up selling it as it was and bought a Caterham Superlight R as a track car and ran that on Yokohama AO48s and Nitron coil overs, that was awesome too.

Great video! When I used to do trackdays, getting a set of (used) slicks was usually the first modification. 6 seconds on a 1:30 lap, with same suspension and same power to weight... all the improvement coming from just braking, corner and corner exit speed. bonkers!

[@OxBlitzkriegxO]

I really appreciate the work you do. I like your honest opinion about the tires you test and I understand why you don't often get to comment about tires across brands versus within brands. On a purely numbers based comparison, track times tell you where brands will rank so long as the platforms are roughly similar. Please continue your testing and keep up the great work.

[@SebiStr99]

This was really interesting! Really looking forward to a more in depth test in the future EDIT: Also would be very interested in suspension damage/wear from using slicks all day on an otherwise stock car, but that probably exceeds the scope of a simple YT video

It does sadly! Rubber bushes would be the main thing to go first, but then I'd be worried about oil starvation etc

[@RobertKarlBerta]

I have noticed that the "same" tire from a given manufacturer can vary from one version matched to a specific car to the "same" tire matched to another car. Pirelli seems to very quite a bit with their PZeros as designed for different car brands/models. I also value a tire that may not be a tiny bit faster than another if the slower tire is actually more communicative. While the older Michelin PSS may be a tiny bit slower dry than a newer P4s....the older PSS, to me, had the better feel and feedback between the two. Also tire tech has changed so much that the newer tires are vastly improved over those of just a few years ago. As far as slicks on a road car....I went with uniballs instead of rubber bushings and that helps with non-slick tires....but I still won't use slicks on my road car....just to many other parts that are getting pushed far beyond their design parameters. I remember reading about a famous competition driver teacher who advised to get less aggressive tires for going to a driving school.....he said you need to learn how to drive the car and not rely on the crutch of a really sticky tire and the slower and cheaper tires give you more warning when you are getting over your head.

Awesome video! The right tyres for the occasion is the only way to improve a new car dynamically and not void your warranty. Have you considered testing lightweight rims + tyres against same size "regular" rims and tyres? Wondering how much reducing unsprung mass would affect performance and grip, especially on a FWD car, where a lot more is expected from the front wheels.

[@tyrereviews]

Yes I have! I'm excited to find a time to test it!

[@pacolicious]

That's a very good question. I'm curious

[@LackundLeder]

@Deniz: Very good question! As far as I know, reducing 1kg each wheel will equal into 28kg less "weight". Reducing 2kg each wheel reduces like 56kg "weight" .. and so on. So maybe not sooo much than you expect. Buuut, if you are able to reduce unused stuff in your car like ChrisFix showed us, plus put some slicks onto it, you´re the king!

[@tire_reviews]

@@LackundLeder Thanks for the link, I'll give it a watch. Rotational inertia is certainly a big deal for longitudinal grip, but less so for lateral so that "56kgs" isn't quite 56 around a track :) It will still be a very interesting test

[@TassieLorenzo]

@@LackundLeder That's way overrated IMO, I think it's more like 1kg of unsprung rotational mass being worth about 4kg. There's a test that a UK magazine did on a Fiesta ST150 years ago. I think the lightweight Team Dynamics wheels with the same tyres were worth about 1-1.5s of lap time compared to the OEM wheels, but the 0-60mph time was slower in the wet with the lighter wheels as there was increased wheelspin (as the lighter wheels reduced the drivetrain loss and therefore effectively increased the amount of wheel horsepower I guess, or maybe just because they had less inertia).

Stiffer springs will work better with rcomps and improve transient response, so on a smoothish track they would be better

[@TassieLorenzo]

I think it depends on how bumpy the track is and how intense the corner loads are. Apparently in the V8 Supercars they run the whole range from 4 kg/mm (so close to a sporty road car) at street circuits where they need to ride kerbs, up to 20 kg/mm (i.e., rock-solid) at circuits like Bathurst where there are high speed corners with elevation change and they need to stop the car bottoming out.

Glad you enjoyed it!

[@ChrisMisMYhandle]

Interesting to see this. One thing that I think a lot of people don't consider when they think of running slicks is the car it was designed for, and the downforce level of that car. If you run a tyre designed to be used on a car with meaningful downforce, you're really going to struggle to load it up enough to get enough temperature into it.

[@larsweinand4035]

Awesome!! Looking forward to more of this. Maybe you can explain the sizes and numbering systems of slicks over standard sizes next time somehow :)

[@tyrereviews]

Good idea :)

[@SerenaBluee]

It looks as though they use the width in mm, outside diameter of the tyre in mm, and the wheel diameter in inches. With the size given as 235/645 R18, an 18" tyre with that kind of profile (similar to the road-biased 245/40 R18 used earlier in the video), would be around 650mm in overall diameter.

[@Fastvoice]

@@SerenaBluee Sounds about right. The Yokohama A005 rear slicks on my old NSX were called 250/610-17 S04. So we have tyre width in mm (which is usually just an approximate value), tyre outside diameter in mm, rim size in inches and compound mix (S for soft, the lower the number, the softer the compound AFAIK).

[@schmid1.079]

When talking upgrades, tyres are the first thing anyone should consider investing in. Doesnt look or sound as cool, but its totally worth buying good ones.

[@russcattell955i]

Tyres & brakes, cheaper than motor upgrades & allow faster for longer.

[@gordonpatterson4425]

I wonder if the compound for the Pirelli P Zero PZ4 changed. Those were my first UHP tires on my Mk7 GTI and tracked them for one day back in 2017. They slide all over the place. Threw them away, after collecting a puncture, and went with the Michelin Pilot 4S. Same set lasted about 6 to 7 track days. They provided much more confidence than the Pirellis. I haven't looked back since.

[@kenzohkw]

Pirelli seem to have poor road tyres. I've seen a set of Pirellis delaminate on a Clio 220 after a few hot laps and they weren't even a year old!

[@tyrereviews]

I think there must have been a big update, I'll check

[@ApothecaryTerry]

Would definitely be interesting to know if they've been updated, there doesn't seem to be any obvious info suggesting that but various forums don't seem to like the PZ4s (although certain forums, especially Porsche ones, are pretty anti-Pirelli anyway) but I stuck a set on last week and have been very pleasantly surprised. They're not perfect but they're certainly better than I'd been led to believe.

[@Dorich55]

Thanks for that video! That was the most entertaining video on a subject that I didn’t think I was interested in, ever. I can only imagine what I felt like to drive that car after changing to track day and then slick tires. Envious here, though it’s looks like you had a long frustrating day at the track. Thanks for the effort. Well done

[@CerberusTenshi]

I might have to look into slicks for my Type R. At least for track use. That would mean different rims to fit the 245/40 tyres, but that's fine, I guess.

[@tyrereviews]

Just be aware things wear out much more quickly!

[@Fastvoice]

@Cerberus: You'll need a 2nd set of rims anyway if you drive to and from the track with the Civic (with mounted slicks in the trunk). 😉

[@CerberusTenshi]

@@tyrereviews True. Most people seem to go through multiple brake pads and even brake disks on track in way less kilometers than my Type R has on it now. Plus oil, bushings and more.

[@CerberusTenshi]

@@Fastvoice I have 18 inch rims for my winter tyres, but those are 235/40. So it's not, that I don't already have a second set of wheels, that I could use for track tyres during the Summer and than put winter tyres on again. They are just the wrong size. Also, over here in Germany, driving on slicks is illegal. I wouldn't be caught dead doing something that stupid.

[@Fastvoice]

@@CerberusTenshi Du hast mich wohl missverstanden. Du kannst problemlos 230-650er 18-Zoll-Slicks (die häufig tatsächlich etwas breiter sind) auf deine 18-Zoll-Felgen montieren und die dann im Kofferraum zur Rennstrecke transportieren und dort montieren. Auch 240-640er gehen. Slicks auf der Straße sind natürlich überall illegal - auch bei uns in Deutschland.

[@marka3504]

Thank you for fulfilling my suggestion with this video, it made my terrible day way better. Now I'm currently looking for some decently used slicks as a start LOLOL.

[@tyrereviews]

Glad I could help!

[@ErikB750]

Would love to see more details (from another test session maybe) taking the temps into the equation. As you know by design, slicks optimal temp is higher, allowing to be more aggressive with the setup and staying out longer, but they might be more limited in the amount of heat cycles they allow. Also storage temps are important (don’t go too low). In short: there’s more than laptimes to think about. (my opinion)

[@JackMott]

not all slicks have higher operating temps. and generally you consider only laptimes and if the life time is less you just pay more money to get new ones more often. such is racing.

[@tyrereviews]

Agreed, I'd love to do all this too but it needs more time (and money :( )

[@ramadhanisme7]

Man this is the comparison that i have been dying to watch for 🤣🤣 Great videos as always, now i can finally see how much the time difference between track tyre and slick tyre

[@tyrereviews]

I hope you enjoyed!

[@peterfarkas6763]

Thank you again for the great content! How did the rim width compare between the different tires? As a side note for future videos topics, I would really like to know if the same width tire would behave any differently with different rim widths or not.

[@tyrereviews]

Wdiths same, different offsets slightly. I actually have that high on my list of things to do as it's something I want to know too!

[@kristinahylton5514]

Tire Rack recently made a video on tire width vs Wheel width. Surprisingly a wider tire is not always faster, and sometimes is slower than a narrow tire on a properly sized rim.

[@CarSceneKorea]

Wish this vid is 30 minutes long. Thanks for the amazing content and props to Pirelli 👏

I once told the police I was on racing slicks. They didn’t believe me.

Well done! I didn't think the differences would be that great.

Don't fit slicks on your track car unless you upgrade your oil circulation system otherwise oil starvation is real and bye bye engine!

Yep!

[@StormeTheGates]

This is awesome! but I'd love to see you throw winter tires in the mix just for fun!

[@videomaniac108]

Thanks Jonathan for another great video. Concerning the use of slicks on the street, I think it is feasible if the driver is really careful. I lived in San Diego, where it is dry most of the year and where there is not a terrible amount of rain during the winter rainy season. I had a Porsche 944s with a set of Yokohama A008Ps that had been evenly worn down to slicks. The tires handled fantastically in the dry during most of the year, with me only having to be watchful for water runoff on the roads from sprinklers. During the winter when we did get some rain I did drive in the slow lane on highways, not over 50, and made gentle turns with light braking and never was in a scary situation. The only problem was when my wife found out that my tires were slicks and she marched me down to the tire store, while ignoring my explanations of how the benefits far outweighed the risks in driving on the sicks.

[@tyrereviews]

Surely it's also illegal past the tread wear indicator of 1.6mm?!

[@videomaniac108]

@@tyrereviews You could be right on that, as I do remember a San Diego cop who was measuring the tread depth of my tires during a traffic stop one day. He was a jerk who was annoyed that some guy who looked like a kid was driving a Porsche and so he was scrutinizing every inch of my car, looking for equipment violations he could stack up against me. I'll not drive the Michelin PS4S tires on my Z past the wear indicators. BTW: my projected mileage for these tires to zero tread is looking like 38K miles on the rears and 50K on the fronts, not what I expected for this kind of tire. The ¢ per mile tire cost of running these tires is looking to be very cheap. I use the engine a lot for braking and have the habit of always trying to use maximum radius turns when cornering; perhaps that's helping in getting the excellent tire wear that I'm getting.

[@DonLee1980]

wow, the tires made such a difference in lap times, but again, this track is like constant cornering and almost no straights. I was debating with a friend the other day, whether track tires made more difference for a fast car, or for a slow car. My first thought was, that a slow car won't be on the limit of grip as much, while a fast supercar will need a good tire to get the most out of the car. Well, this test showed that even a good tire on a medium fast car will improve your lap time hugely, but again, it could be circuit dependant. Gosh, I still don't know lol, but thank you for this test!

[@stephenlongfield8492]

Trofeo R tyres are my favourite track tyre atm, the wear rate on them is awesome even when you push them HARD 👍

[@winkytct]

Thank you for doing this video! (Would love to see the Yaris GR test)

[@zoominalways]

pls tell me what psi where the tires at

[@stefndogg]

Once again another super useful comparison. I have thought about going the slick route a few times(currently on Rival S 1.5's), but as you mentioned, the wear and tear on wheel bearings, bushings etc. always kept me away. Back before all the "200tw" tires were out, I ran Toyo Ra1's on my cars, which were the hot tire at the time, but even those were very hard on suspension components. These days, I feel like unless its a full time track car, the current crop of 200tw tires strikes a good balance between on track ability and street usability. If I ever can justify having truck, trailer and full time track car, then I will for sure go with slicks.

[@tyrereviews]

I'd imagine the 1.5's are pretty tough too!

[@tamarockstar09]

Seeing that tire lift up from the ground in your turns brought back memories of almost flipping over lol

[@TheChannel1978]

Great test! Have been wondering about this myself. Long time user of semi slicks but never made the jump to slicks, because I drive to the track.

[@Eddie07S]

Quote of the day - “So where where was it (the slick) getting time from? Absolutely freakin’ everywhere! It was awesome!” 👍 Actually, I am surprised you saw much of an improvement with the slick. With as little front camber as that car probably has, it is no wonder that the slick didn’t pull itself off the tread and onto the slide wall and understeeer to the point of agony. The car did well. The thing I wonder about with slicks as a track day tire is whether they will heat cycle out before wearing out. If I do a 2 day event, that would be 8 heat cycles. I wonder if they will be at a 500 TW before the end of the event. At any rate... great review. Looking forward to the followup...

[@tyrereviews]

I'd really like to test that, but I'd guess it wildly varies from slick to slick

[@Eddie07S]

True if you were looking for absolutes in changes in performance. But what if you were to just look for a trend within one brand? Could you get a trend just though changes in tread rubber hardness? What if you took the PIRELLI track tire and slick to multi tire test days that you do even if the tests themselves are for some other reason. It wouldn’t have to be the same track, maybe not even the same car, but just to heat cycles on them; tag along laps/testing. Take hardness measurements after they cool each time, Maybe tire temps as you come off the track? Then after a few heat cycles take them back to the track that you first used them and retest them for lap times. Ok, surely there are some details to work out along with how to compare data, but maybe a trend can be worked out. Just a thought... At any rate, your efforts are always of interest...

[@997speedy]

Epic video, amazing difference from the track tyres to the slicks. Would you ever do a video explaining speed ratings, e.g. why the same tyres have different speed ratings, what difference it makes, how its tested, what is the real limit? (as i unknowingly went 162mph on a 130mph rated winter tyre :/ ).

Sure, I'll put it on the list

[@tome1903]

My autocross truck went from sliding through turns with barely any lateral G force on street tires to having so much grip with the slicks that i got a new rule added because i almost rolled the truck and it would frequently 3 wheel. Ive since lowered it to the point that almost rolling is no longer an issue, but it will still happily pick up the inside front tire, and I'm getting ready to put an even grippier set of tires on it.
